On the Compared Expressiveness of Arc, Place and Transition Time Petri Nets
In this paper, we consider safe Time Petri Nets where time intervals (strict and large) are associated with places (P-TPN), arcs (A-TPN) or transitions (T-TPN). We give the formal ...

Theoretical analysis of singleton arc consistency and its extensions
Singleton arc consistency (SAC) is a consistency property that is simple to specify and is stronger than arc consistency. Algorithms have already been proposed to enforce SAC, but...
